Description
Technical field
A kind of heating of the present invention belongs to field of temperature control with the device of refrigerating flowing liquid, particularly be the device that is applied to Fast Heating and refrigerating flowing liquid temperature.
Background technology
Directly fuel liquid battery is the Blast Furnace Top Gas Recovery Turbine Unit (TRT) that a kind of chemical energy that directly will be stored in liquid fuel and the oxidant efficiently, contamination-freely is converted into electric energy.It is efficient with it, environmental protection, energy density height, store outstanding advantages such as easy to carry, is considered to the ideal source of portable electric appts, is subjected to attention more and more widely.
Fuel cell technology is in development, and the factor that influences direct fuel liquid battery practicability mainly contains: the ratio of performance to price is low, and the reliability and stability of long-term work are undesirable.The influencing factor in battery performance and life-span, except the membrane electrode material and preparation technology, battery structure design and packaging technology of battery, service conditions such as temperature and flow all can produce appreciable impact to the performance and the life-span of battery.The humidifying of battery operation temperature effect catalyst activity, film, the mass transfer of inside battery and the heat balance of battery.Temperature effect battery life that liquid fuel is too high even damage battery, low excessively temperature then has a strong impact on the performance of battery.The mass transfer of the flow effect inside battery of direct liquid fuel, the too small meeting of flow causes the anode fuel undersupply, causes the concentration polarization of battery; Can increase the channelling of anode fuel from the anode to the negative electrode and flow is excessive, thereby the cooled catalyst surface temperature reduces catalyst activity simultaneously, reduce fuel cell performance.In the running of fuel cell, temperature is different to the performance impact of battery with flow under the different operating modes.Therefore, in the process of operational factors such as research temperature and flow, need the temperature and the flow of controlling liquid fuel to battery performance and life-span influence.
At present, liquid heater has various ways, but majority is the heater that is used for inactive liquid.Chinese patent ZL200520109719.5 has introduced a kind of heater that heats when liquid flow, adopt the liquid in several electric heating body heated quarty tube.Comprise a tubular heat-resistant tube and a plurality of electric heating body.Wherein quartzy heat-resistant tube inside is provided with the calandria cavity volume of several separate space, and the flow channel for liquids in each calandria cavity volume all communicates with the interior flow channel for liquids of adjacent calandria cavity volume.And in each calandria cavity volume, be provided with electric heating body.When flow of liquid is heated by electric heating body during through the runner of quartz ampoule inside, the liquid of design temperature flows out from delivery line.The cavity volume that is heated fluid in the whole heater is bigger, if having additional supply of electric power to electric heating body, then needs the liquid of the output design temperature that one period long period could be stable after predetermined temperature is set.After turning down, design temperature need the long period could stablize the liquid that the back temperature is adjusted in output equally.U.S. Pat 5381510 discloses the working fluid heater of another kind of form.It has a flat board that has the serpentine flow structure, and a dull and stereotyped end leaves the inlet of serpentine flow, and the other end leaves outlet.Dull and stereotyped upper and lower surface is used for the crossfire between heat conduction and partition adjacent channels closely with the flexible aluminium foil that is easy to heat conduction, and the outside of each aluminium foil is a heating plate.Heating plate heats the dull and stereotyped fluid of going up serpentine flow of flowing through by aluminium foil.But the too big heats that influences of the size of serpentine flow, the too little flow field difficulty of processing that then increases of size, and also the sealing of dull and stereotyped and aluminium foil is relatively more difficult.
